LUBRICATO R.

SPECIFICATION forming part of Letters Patent N 0. 636,185, dated October31, 1899.

Application filed March 8, 189 9- To all whom, it may concern.-

Be it known that I, GEORGE H. W. RUNGE, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Lubricators, of whichthe following is a full, clear, and exact description, reference beingbad to the accompanying drawings, forming part of this specification.

My invention relates to a lubricator by means of which a continuous feedof oil may be'effected through various conductors leading to variouspoints, the flow of oil being maintained by means of compressed air andspring-pressu re exerted thereon.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a perspective view showing my improved lubricator. Fig. IIis a vertical sectional view taken through the oil-reservoir andcompressed-air chamber.

1 designates an oil-reservoir having an inlet 2, closed by a cap 3. Tothe lower end of this reservoir is fixed a discharge-pipe 4.

5 designates a chamber into which air may be introduced and compressed,the said chamber having communication with the reservoir 1 by aconnecting-pipe 6. The chamber 5 is supported bya cross-piece 7 and theconnect ing-tube 6.

Within the chamber 5 is, a piston 8, supported on a coil-spring 9, thatrests upon a removable cap 10, secured to the lower end of the chamber.At the upper end of the chamber is a nipple 11, the end of which isclosed by a removable cap 12, and from this nipple into the interior ofthe chamber communication is controlled by a springcontrolledcheck-valve 13, that prevents the escape of air from the interior of thechamber after it has been forced therein by means of a suitable pumpapplied to the nipple 11 on the removal of the cap 12. The pipe 4contains a valve 14.

15 designates cocks that may be located in any desirable positions Wherethere are journals to be-lubricated, these cocks being provided withset-valves 16, by which the quan tity of oil flowing through the cooksmay be controlled to a nicety, so that any desired feed of oil may beattained. The cocks are Serial No. 708,260. (No model.)

In the supply-pipe 18 are bends 19 and 20.

Between the bends 19 and 20 is a union 21, containing a turn-joint thesleeve of which is held in place bya set-screw 22. The pipe 18 isconnected to the discharge-pipe 4 by a union 23, containing a turn-jointthe sleeve of which is held in place by a set-screw 24. By providing thebends 19 and 20 in the supply-pipe 18 and introducing the loose unions21 and 23, that provide for a universal movement of the parts withrelation to each other, either part may be mounted on a movable supportwithout the moving of such support effecting the operation of thedevice.

This lubricator is well adapted for use in supplying lubricant to thejournals of caraxles, or it may be used in lubricating journals of anyother description. The coupling 18 of the supply-pipe 18, by which itisjoined to the delivery-pipes 17, is provided with an extra arm 18, bywhich a second set of cocks may be connected by suitable piping to thesupply-pipe 18 and be fed therefrom.

In the operation of this lubricator the res= ervoir 1 is filled with oiland air is pumped into the air-chamber 5, so as to be compressedtherein, by attaching a pump to the nipple 11 on the removal of the cap12. In compressing the air into the chamber 5 the piston Sis forceddownwardly,contraoting the spring 9 and moving the piston to the lowerend of said chamber. The valve 14 is then opened when it is desired tostart the flow of oil to the cooks 15, and the pressure of thecompressed air fiowing from the chamber 5 through the pipe 6 into theoil-reservoir presses the oil out of the reservoir gradually, causing itto flow through the pipes 4, 18, and 17 to the cooks 15 and feeding itto the journals to be lubricated.

I claim as my invention-- 1. A lubricator comprising an oil-reservoir, adischarge-pipe leading from the reservoir, a compressed-air chamber, apipe of less diameter than the reservoir and chamber, connecting thecompressed-air chamber with the oil-reservoir, and the spring-pistonlocated 2. A lnbricator comprising an oil-tube havcoil-spring, and thepipe connecting the up 16 ing an inlet at the upper end of the tube, aper ends of the oil-tube and air-tube and of cap closing the inlet, adischarge-pipe fixed less diameter than the said tubes; substanto thelower end of the oil-tube, an air-tube tially as described.

5 having a nipple at the upper end of the air- I tube, a cap closing thenipple, a spring check- GEORGE RUNGE' Valve controlling the nipple, thecap closing In presence of the lower end of the air-tube, the springseated H. F. RIDDLE, on the lower cap, the piston support-ed on the 1 R.M. RIDDLE.
